文件上传 乱码
所有字符集都设置的是utf8，但上传文件后在文件目录下发现中文文件名乱码，然后就在上传前把文件名转为了GB2312码，这时候文件名可以显示中文了，但是数据库存放路径的时候不能插入了，我就把那张表改成了GB2312的字符集，按理说这样就可以了吧，还是插入不了？怎么办回复讨论(解决方案)
这里涉及两个概念，系统的编码和字符的编码
不知道你上传前是什么系统，如果是windows（98以后），选了"gb2312"编码实际上是cp936（相当于GBK）编码
而数据库的字符编码gb2312和gbk并不相同，汉字少很多，应该选gbk编码
还不行的话就要考虑其他因素了，如果服务器是windows，那是个麻烦事，因为php目前还不能有效处理windows下unicode路径??假设你的全路径有任意一个字符超出了字符集，windows是采用混合编码记录路径的；而*nix则是统一以utf-8编码记录路径，所以问题不大
csdn的开发人员又做多余的事了，帖子的分段又没了，唉……
说一个解决思路楼主试一试
还是全用UTF-8,上传后在PHP文件内再强制转换一次 上传后检测文件名是UTF-8还是GBK还是GB2312 然后统一转换为UTF-8
参考 http://www.cnblogs.com/rosenia/archive/2013/05/20/3088146.html 数组多加一个GB2312
然后再存
